Application Type 1 represents the maximum capacity to achieve 100% braking torque when possible. Application Type 2 indicates that the braking torque may exceed 100%, up to a maximum of 150%. Always check the resistance ohms against the minimum resistance of the driver being used. 33 33 68 68 31 117 117 48 48 Drive input voltage Braking resistor Ω Rack category.
